Verified content
- [abstract] 11 unique studies (17 records, 297,994 participants) of students aged 13–19; randomised trials, controlled before-and-after and interrupted time series studies eligible.
- [abstract] Quality of the body of evidence very low; the authors could not be confident about the effects of later start times.
- [abstract] Four studies examined academic outcomes, with mixed results; six studies found significant positive relationships between later start times and amount of sleep.
Limits
- [assessment] Read at abstract level only (full review not read tonight); searches end February 2016, so later studies such as Dunster et al. 2018 and James et al. 2023 are not included.
Added 2026-10-17 by the project (nightly attack run). [abstract] = from the published abstract; [full text] = read in the full text; [assessment] = the project's own assessment.
